Claims

1. A loader gearbox output flange structure comprising a brake disc (1), a brake assembly (2), a bolt (3), a nylon self-locking nut (4), an output flange (5), an output shaft (6), a cross shaft (9), a transmission shaft (10); characterized in that, It also includes a fixing plate (7) and fixing plate bolts (8). The output flange (5) is an open output flange with a large end face (5-1), a semi-circular groove (5-2), an open end face (5-3), and a boss (5-4). The open output flange (5) and the output shaft (6) are connected by a spline fit and are locked by a nylon self-locking nut (4) to achieve end face fixation. The brake disc (1) is installed on the large end face (5-1) of the open output flange and is locked by multiple evenly distributed bolts (3). The two end faces of the brake pads of the brake assembly (2) are fitted with the brake disc (1) with clearance. One shaft of the cross shaft (9) is mounted on the semi-circular groove (5-2) of the open output flange, and the end face of the cross shaft (9) is limited by the boss (5-4) to prevent movement. The other shaft of the cross shaft (9) is engaged with the semi-circular groove of the input flange of the transmission shaft (10). The middle part of the fixing plate (7) is arc-shaped, and the two sides of the arc shape are flat. The flat surface is flush with the open end face (5-3) of the open output flange. The arc surface is flush with the arc surface of the cross shaft. The fixing plate (7) is then locked on the open end face (5-3) of the open output flange by the fixing plate bolts (8) to fix the cross shaft (9).
